Trouble is, I have install a trial version of CS5 before I realised that Dreamweaver should have been there with my CS3. Should I uninstall my trial version? Also, should I uninstall CS3 and re-install it. Or can I put the CDs in and re-install?

I am in Windows. Not sure why I can't upload the screenshot. I can see the camera icon, and as I work as a document controller and am very used to uploading documents - can't understand why I can't upload this one.
